7-hour sleep helps high school students do
better

Washington: High
school students seem to do better in studies when they have seven
hours of sleep, rather than nine recommended by federal
guidelines, a study reveals.
"We're not talking about sleep deprivation, the data simply says
that seven hours is optimal at that age," said study co-author
Eric Eide from Brigham Young University (BYU).
The new study, led by Eide and BYU economics professor Mark
Showalter, is the first in a series where they examine sleep and
its impact on our health and education.
Surprisingly, the current federal guidelines are based on studies
where teens were simply told to keep sleeping until they felt
satisfied, said a university statement.
"If you used that same approach for a guideline on how much people
should eat, you would put them in a well-stocked pantry and just
watch how much they ate until they felt satisfied," Showalter
said. "Somehow that doesn't seem right," he added.
Analysing data from a representative sample of 1,724 primary and
secondary school students across the country, they found a strong
relationship between the hours of sleep youths got and how they
fared on standardised tests.
"We don't look at it just from a 'your kid might be sleeping too
much' perspective. From the other end, if a kid is only getting
5.5 hours of sleep a night because he's overscheduled, he would
perform better if he got 90 minutes more each night," Eide said.
The size of the effect on test scores depends on a number of
factors, but an 80-minute shift toward the optimum is comparable
to the child's parents completing about one more year of
schooling.
